I”m experiencing the same issue, WordPress 4.5.2 and ACF Pro 5.3.0, the Custom Fields are displayed on the left side on my custom taxonomy but not when I try to edit a term. I already disabled every other plugin to exclude an issue with one of them and I don’t have any java script errors in my console, only this probably unrelated notification:
load-scripts.php?c=0&load=jquery-core,jquery-migrate,utils,underscore,wp-util,wp-a11y,updates&ver…:9 JQMIGRATE: Migrate is installed, version 1.4.0
